The 'Voice USA' mentor, 46, who celebrated Halloween with the hunk in Los Angeles last weekend, is remaining coy on whether she's dating her newly-single co-star, 39, but has admitted she does find him very attractive.

Speaking on KISS FM's 'On Air With Ryan Seacrest', she said with a cheeky giggle: "[I] think he's hot, don't you?"

Despite insisting she's not ready to address the romance rumours "right now," the blonde beauty has revealed the talented duo have been comforting one another following their divorce from their former partners earlier this year.

She explained: "To be super honest, it is kind of crazy we both went through the same thing at the same time.

"There's been so many people that I've got so much comfort from. Just people coming to me and telling me their story, not confiding, but sharing, which has just helped me see things from a different perspective and move forward."

Meanwhile, Gwen recently admitted she felt like she "had been living in a cocoon" before her split from Gavin Rossdale, with whom she has three sons, Kingston, nine, Zuma, seven, and 20-month-old Apollo, and was suffering from severe writer's block before they separated in August after 13 years of marriage.

Blake, on the other hand, has also been venting his emotions in the recording studio following his divorce from Miranda Lambert in July after four years of marriage.
